Moldable Exceptions

Published in Proceedings of Onward! 2024, 2024

In this paper we introduce “moldable exceptions”, a lightweight mechanism to adapt a debugger‘s interface based on contextual information provided by a raised exception.

Automated Generation of Code Contracts — Generative AI to the Rescue?

Published in GPCE 2024: Proceedings of the 23rd international conference on Generative programming and component engineering, 2024

This paper examines the potential of Generative AI to automatically generate code contracts in terms of pre- and postconditions for any Java project without requiring any additional auxiliary artifact.

Example-driven development: bridging tests and documentation

Published in Live 2024, co-located with SPLASH 2024, 2024

We show (i) how Example-Driven Development (EDD) enriches TDD with live programming, (ii) how examples can be molded with tiny tools to answer analysis questions, and (iii) how examples can be embedded within live documentation to make a system explainable.

The Hidden Costs of Automation: An Empirical Study on GitHub Actions Workflow Maintenance

Published in SCAM 2024 (IEEE 24th International Working Conference on Source Code Analysis and Manipulation), 2024

This paper presents a large-scale empirical investigation towards characterizing the maintenance of GA workflows by studying the evolution of workflow files in almost 200 mature GitHub projects across ten programming languages.

Moldable Development Patterns

Published in Proceedings of EuroPLoP 2024, 2024

Based on several years of experience of applying moldable development to both open-source and industrial systems, we have identified several mutually supporting patterns to explain how moldable development works in practice.

Exploring GitHub Actions through EGAD: An Experience Report

Published in International Workshop on Smalltalk Technologies (IWST 23), 2023

We present our experience developing and using EGAD (Explorable GitHub Action Domain Model) and share valuable insights we gained. Our focus is on three key areas: (i) onboarding of Glamorous Toolkit (GT), (ii) creating a comprehensive and explorable domain model of GA, and (iii) highlighting the potential of EGAD as a research workbench.

EGAD: A moldable tool for GitHub Action analysis

Published in 14th International Conference on Mining Software Repositories (MSR 2023), 2023

We present our preliminary steps in building EGAD (Explorable GitHub Action Domain Model), a moldable domain-specific tool to depict and analyze detailed GA workflow data.
